What is Calcium lactate?
Calcium lactate (CAS 814-80-2), also known by its food additive designation E327, is a calcium salt of lactic acid produced through fermentation or neutralization processes.
Where is Calcium lactate used?
- Food production: firming agent for fresh-cut fruits and vegetables without the bitterness of calcium chloride
- Beverages and supplements: bioavailable calcium source for fortified drinks, chewable tablets and effervescent formulations
- Pharmaceutical compounding: oral calcium supplements and antacid preparations
- Personal care: buffering agent in toothpastes and mouthwashes
- It also functions as a pH buffer and calcium fortification source.
Good to know: Pentahydrate is the most common form; anhydrous grades are available for moisture-sensitive applications. Consistent purity and dissolution behavior affect product performance.
Commercial specifications
- Standard grades: FCC, USP, BP, Ph. Eur.
